    摘要： Both an apparatus and a process for accurately applying a correct amount of brazing heat to a conduit are disclosed herein. The apparatus generally comprises a mandrel including an electrical resistance wire heating element and a heat sensor for sensing the temperature of the inside walls of the conduit which were heated. The mandrel is preferably formed from a refractory material, and the heat sensor is located beneath the surface of the mandrel in order to insulate it from heat radiated from the electrical resistance wire wound about the mandrel body. The mandrel further includes an opening in the portion of the mandrel which surrounds the heat sensor in order that the sensor may be selectively exposed to a section of conduit to which heat was applied by sliding the mandrel to a position which aligns the opening with the wall of the heated conduit. The temperature of the conduit may then be determined as a function of the radiant heat received by the heat sensor. The invention is particularly useful in producing high quality braze joints between reinforcing sleeves inserted within damaged heat exchange tubes of a nuclear steam generator since the heat sensor allows the operator to determine whether or not a proper amount of brazing heat was applied to the sleeve/tube configuration.

    摘要： An induced current heating probe is of thimble form and has an outer conducting sheath (30) and a water flooded flux-generating unit formed from a stack of ferrite rings (10) coaxially disposed in the sheath. The energizing coil (14) is made of solid wire which connects at one end (16) with a coaxial water current tube (15) and at the other end (17) with the sheath. The stack of ferrite rings (10) may include non-magnetic insulating rings (11) which help to shape the flux.

    摘要： A method and apparatus for hardening a small internal passage in a workpiece wherein the workpiece is indexed into coaxial alignment between axially spaced inductor coils and an actuator telescopically inserts a magnetically permeable flux concentrating rod through the passage, and coextensive with the coils and in inductive relationship with the interior surface, such that upon energization of the coils, flux is concentrated in the concentrating rod and effectively inductively delivered to the surface to raise the temperature thereof to a heat treating temperature, the actuator being extended to another position wherein a quenching ring is disposed adjacent to the surface for delivering coolant thereto to quench harden the surface, the actuator being finally retracted to allow sequential indexing of workpieces.
